The Project I was recently working on a project to expose our trading systems via XmlRpc, Rest and SOAP. It was quite an interesting project, which took two of us three weeks to develop (Amongst other things). This involved creating a testbed, that would automatically generate the payload and response for each protocol. The parameters […]
In high performance web applications you will always have bottlenecks within your application. Identifying these bottlenecks and optimizing is a tedious task and typically show themselves underload. A single bad/unindexed query can bring a server to its knees. A large number of rows will also help to highlight any poor queries, and on very large […]
Recently I had to install memcache on a number of servers, and I would always tend to end up with errors whilst memcache tries to locate libevent. I always seem to forgett LD_DEBUG, so I figured I would write up the process for installing memcache. One of the dependencies of memcache is libevent, so firstly […]
Introduction Currently I’m working with stock market data, and its quite an interesting topic when we are getting to the point of real time data as it brings a number of new concepts into the mix. The first challenge is to import information from the feeds into our databases (MySQL), whilst this should be a […]
recently read “Binaries Belong in the Database Too” on sitepoint.com, and thought I would shed some light with regard to my experience of storing files in databases. I’m sure many of you have known this to be a taboo practice, and I would certainly agree depending on the database. A project I worked on for […]

1 Aug 2006It’s been some time since I last posted, due a rather hectic schedule and today I fly off to Loret De Mar, Spain for a week with the lads and two weeks after that to Miami. I’m sure this will help to take my mind of things. As with anything you constantly learn from your […]
I wrote this a while ago, whilst playing with SQL Injection, however a little unfinished, the idea was to try to write out entire files, through an SQL Injection attack. I thought I would expand, on my previous post Exceptions, Exceptions, Exceptions, and see what is possible with a simple a SQL Injection attack. I […]

27 Mar 2006Well, i’ve been rather busy at work, which is nothing short of typical now, however I thought I would post up a script that I wrote to automate the installation of PHP on Windows. In general I’m a very lazy person, and found it irritating going to the PHP site, downloading and manually installing PHP […]

14 Mar 2006After upgrading to the very latest build of Plesk the API error seems to have been resolved, and no longer causes an API error of “Domain adding was failed. Error: Can`t resolve ID for IP ()“. Previously: [Server 3]# rpm -qa |grep -i psa-api | sort psa-api-cli-7.5.2-rhel3.build75050130.17 psa-api-common-7.5.2-rhel3.build75050130.17 psa-api-rpc-7.5.2-rhel3.build75050130.17 psa-api-rpc-doc-7.5.2-rhel3.build75050130.17 psa-api-rpc-protocol-7.5.2-rhel3.build75050130.17 Now: [Server 3]# rpm […]

12 Mar 2006I found this a little amazing, but SWSoft don’t actually fully support their own software. “Unfortunately, SWSoft does not fully support the API that is built in to Plesk and more than likely, they will request that we first perform an upgrade to the latest version of Plesk before they provide any further support.”, Rackspace.

I have been a developer for roughly 10 years and have worked with an extensive range of technologies. Whilst working for relatively small companies, I have worked with all aspects of the development life cycle, which has given me a broad and in-depth experience.
